Over 650 million spectators are expected to watch El Clasico on television, but it is the roughly 80,000 at the Estadio Santiago Bernabeu who will be even closer to the action, with supporters flocking in from across the globe.

Most will be from Spain for obvious reasons, but plenty of nationalities will fly in for the big game, with Mexico chief amongst them.

Both teams North American tours have had a dramatic impact, as the countries after Spain that have sold the most Clasico tickets are the United States, Canada and Mexico.

"To attend this event is the dream of many," said Stubhub Argentina director Irene Recio.

In Mexico in particular there has been a 30% increase in demand for tickets over the past three seasons.
